' fmumm L. Jansen ill/s :rrmmzr portions 9 on the sides of the frame member. The members 15 have the portions thereof below the pin 14 and adjacent the frame member, formed as a gear segment having the radial teeth 17 formed thereon, which teeth are adapted to engage with the teeth 9 o the rack formed on the frame member.

In operation, the bearing will normally occupy the position shown in Fig. l. \Vhen relative movement occurs between the hearing surfaces on the bolsters which engage the hearing rollers 11). the rollers will be moved and will traverse in one direction or the other on the bearing plates. This movement will be transmitted to the plates 12', and by them, to the upper part of the counterweight members 1;). Owing to the engagement of the teeth on these members with the rack on the frame member, said members cannot move bodily longitudinally, but will be turned angularly about the pin 14 and the counterweight portion thereof elevated. Such elevation position of the counterweight is illustrated in Fig. 4 where the rollers are shown at approximately the limit of their movement. The members 15 will tend to swing downwardly by gravity. and as the surfaces engaging the bearing rollers 10 resome their normal position, the counterweight members will assist the rollers 10 in returning to their central and normal position.

it will thus be seen that applicant has roduced a simple and etlicient roller side 'iearing. The parts of the bearing can all be readily made as steel castings or forgings and the construction is such that the part will require very little machining. It wil of course, be understood that various changes may be made in the form, size and details of applicants device without departing from the scope of the invention, which. generally expressed. consists in the matter shown and described and set forth in the appended claims.

What is claimed is:

l. A side bearing for railway cars having in combination a frame member comprising a housing, a pair of bearing rollers disposed in said housing connecting means for said rollers holding them in spaced relation, oscillating connterweights carried at the outer side of said housing, means engaging said connecting means and said counterweights, and means on said housin engag ing said colinteriwiglits whereby said counterwcights will he swung and moved out of normal position when said bearing rollers are moved.

'2. It side bearing for railway cars having in combination a frame member comprising a housing, a plurality of bearing rollers disposed in said housing. countcrweights mounted without said housing, and means including a rack on said housing for moving said counterweights out of normal pottion when said rollers are moved from normal position.

3. A side bearing for railway cars hav ing in combination a frame member comprising a housing. a plurality of rollers disposed in said housing having central openings therethrough, a connecting member to said rollers having means engaging said central opening to hold the rollers in spaced relation, :1 pin passing centrally through said connecting members and between said rollers and projecting on either side of said housing, depending counterweight members loosely mounted on said pin at each side of said housing, and means on said housing engaging said counterweight member whereby the same will be swung on said pin when the hearing rollers are moved out of normal position.

4. A side bearing forrailway cars comprising a frame member, a bearing plate carried thereby, a pair of rollers supported on said plate having central openings therethrough, an elongated bar at each end of said rollers having spaced projections thereon engaging in the central openings of said rollers to space the same counterweight means, and means connecting the same to said bar.

5. A side bearing for railway cars having in combination a frame member, counterweight members suitably supported at each side of said frame member, each having a. gear segment formed thereon, a horizontal rack at each side of said frame member with which the teeth of said segment engage, a plurality of bearing rollers disposed in said frame member, and means connecting the same to said counterweight member, whereby said members will be moved out of normal position upon movement of said bean ing rollers from normal position.

(i. A side bearing for railway cars having in combination a frame member comprising a housing having side portions, a plurality of bearing rollers disposed in said housing, a pin passing transversely through the sides of said housing between said rollers, counterweight members swingingly mounted upon said pin 'at each side of said housing and being formed with a gear segment adjacent said housing below said pin, a rack member formed at cach side of said housing with which said segments engage, and means for transmitting the movement of the rollers to said pin, whereby the counterweight members will be swung thereon when the rollers more out of normal position.

7. side bearing for railway cars having in combination a bruising. a plurality of bearing rollers supported therein, counterweight mcinbers supported to be bodily moved and also swung about their supports, and means for bodily moving and swinging said counterweights upon movement of said bearing rollers.

8. The structure set forth in claim 8, said last named means including engaging means on said housing and coui'iterin 'eights.

9. A side bearing for railway (flIS comprising a housing, a plurality of bearing rollers supported for movement therein, means connecting said rollers and a counterweight mounted for bodily and swinging move- 10 ments upon movement of said rollers to return said rollers to their normal position.

In testimony whereof I afiix my signature in presence of two witnesses.
